Do not confuse popular veneration with official Church sanction.
There are many things the Church rejects - or at least, doesn't accept. Even making saints has been an arduous process.
Hey, I'm interested in art. Sometimes I might see The Thinker in a cloud formation.Does that mean the director of Musee Rodin should come over here & slap a gag order on me? The RC Church is most certainly not a democracy but it's hardly a repressive dictatorship that controls members' thoughts & actions around the globe.
I don't think it's really fair to extrapolate from this that these people are seeking validation for their faith in the cookie sheet or that they're venerating it in any way either.
In fact, to 'see' that here would require an imagination at least as overactive as these folks', I dare say.
